It would be great if the LED brightness settings would show what the levels are changing.

When I originally downloaded the app, it would connect the grow light via Bluetooth, and I would hold the Wifi button, and it would not allow me past the screen to connect via my Wifi. I contacted support, and then an update came out, which allowed me to get to Wi-Fi networks. I have several 2.4 GHz networks, and each time I get to connecting, it then shows the check marks that it has made it past 1. Sending WiFi Configuration, 2. Connecting to Router, and then it says Upgrading Firmware, and then it states Response Timeout. I had contacted the customer service several times, and they just responded to you with the most basic troubleshooting when, in fact, it is either the app itself not communicating properly or a bad grow light remote. It has been a complete nightmare. The last thing they asked me to try was using my phone as a mobile hotspot, and guess what... same issue where I make it to Upgrading Firmware and the same issue, response timeout. On my router, I even had 5 GHz disabled, and even on my TP-Link, where it is 2.4 GHz only. I think you should be like any smart device: connect to the smart device and then upgrade the firmware later. I have even connected new smart light switches that only use 2.4 GHz, so why isn't this thing connecting?!!! It is definitely the remote or the app. Something needs to be fixed, as I have spent days trying to connect this grow light. I have even told them the remote itself, without trying to connect to WiFi, does not turn on or off when you press the button to do so. It is like they ignore the fact it does that, and I was hoping if I connected it to the app, it would allow me to turn it on or off.

I bought my grow-light off Amazon. Its been great. The App has been working great. My only problem with the product is that when its set at a low light level sometimes it has an incredibly high pitch sound emanating from it.
